TM 1860 & TM 1863

Extreme Heat Resistant Mica. 1860=TerMica, 1863=TerMica M

Applications

Style TerMica and TerMica M material excels in the most extreme heat conditions, and is used in difficult sealing scenarios such as exhaust, hot gas and silencer applications.

TerMica

Construction

Style TerMica is an extreme heat resistant material. This premium phlogopite mica material is not prone to significant weight loss in elevated temperatures, allowing it to maintain sealing ability in the most challenging applications.

Style TerMica M is premium phlogopite mica with a metal reinforced perforated stainless steel core. This provides good recovery properties and load retention, for long-term sealing ability and also improved pressure resistance.
